    why we can not use the ferrite core as a choke
    thanks

    You can.
    A "choke" is an inductor having a relatively high impedance, used to prevent the passage of high frequencies.

    If you salvage components from discarded electronic equipment like satellite television tuners, you may find that internally, the AC power wires are wrapped several times around a toroid. The toroid will have a high Al value to keep high frequencies from passing along the wire; resisting both ingress (incoming RF signals) and egress (outgoing RF signals).

    Hello,

    Have a look in the following PDF:
    rf_proto-1.pdf

    From page 8 and on there is a description of the RF chokes.
